A cross-platform corpus analysis toolkit for concordancing and analysing texts encoded in Unicode. AntConc specialises in creating concordances, but the developer's software page provides many tools for other tasks, such as AntCorGen for corpus creation, AntFileConverter to convert PDF and Word (DOCX) files into plain text for use in corpus tools like AntConc etc.
